I encourage you not to give up, but if you are one of those who become convinced that the puzzle is impossible, send me $10.00 and I will send you a disk that will cause the puzzle to solve itself. Send the check to:

David B. Howorth 01960 SW Palatine Hill Road Portland, Oregon 97219

Checks only. Specify 5 1/4 or 3 1/2 disk. I'll include any updates of STOPSIGN as well as the current version of its predecessor, ARGH.
